GitLab

Updated version from 1.8.1 to 1.10.0.

Added [gmock|gtest]_all.cc to PIO ignore list to avoid getting duplicate
symbols since PIO will compile the individual files.

Improved flexibility by removing the Arduino entry points in favor of manual calls to setup/loop that the user can call from their entry point.  This is the more common use case for Arudino.

Also added the gtest/gmock_main files to the PlatformIO ignore list since we are not supporting that feature.

This is still a work in progress.

Added initial library.json config for PlatformIO

Version will be synced to proper googletest version once the PIO library has been registered and proven out round trip.
